Title: Digital mobile radio equipment
Inventor: FUJIMOTO YUKIHIRO
IPC: H04B7/26
Filed: 1994-05-17
Abstract: PURPOSE:To reduce a consumption power properly based on the sense of hearing of a user corresponding to the sound state and the soundless state at the side of the transmission and the reception. CONSTITUTION:Based on the level of the output voice signal from an AD converter 2, the sound/soundless state at the transmission side is decided. The signal accepted at an antenna 6 is converted into a base band. Based on the coding voice data outputted from a reception part 7 which demodulates data at the output, a reception soundless detection part 9 decides the sound/soundless state at the reception side. Based on the decision result, a control part 14 is operated. The control part 14 controls the operation of a voice encoding part 4 which executes the encoding of the digital voice signal by selecting either of the normal or simple system, transmission part 7, a voice decoder 8 which executes the decoding of encoding voice data by selecting either the normal or simple system and a pseudo noise generation part 13 which generates the pseudo noise.

IPC: H01L31/04
Filed: 1979-08-13
Abstract: PURPOSE: To obtain a device without variations in thickness and height of a junction barrier and deterioration of its optoelectro conversion efficiency, when preparing an optoelectro conversion device by providing a P-N junction or a PIN junction on a substrate through a light transmissible and electroconductive layer, by composing the light-transmissible layer of nitride.  
     CONSTITUTION: A-light transmissible electroconductive layer 2, which is composed of an indium oxide, a tin oxide and an antimony oxide, etc. containing 0.1∼10% of tantalum, tungsten and molybdenum, etc., is attached onto a transparent substrate 1 such as a glass, and onto this layer 2 a light-transmissible and electroconductive lager 3, such as tantalum nitride, tin nitride and antimoly nitride, etc., is attached to the minimum current-passable thickness ranging 5∼100Å. And then, 6 layers 4a through 4f of P + , N, P, N, P, N +  type using semiconductors are made to grow on this layer to form 5 P-N junctions, and these junctions are covered with an electroconductive layer 5. It is possible, by doing so, to obtain a solar cell whose optoelectro conversion efficiency is not deteriorated even if it were to be operated for a long period of time at a high temperature.

Title: Production for magnetic disc
Inventor: FUKUSHIMA SHIGERU
IPC: G11B5/84
Filed: 1985-05-15
Abstract: PURPOSE:To obtain a disc which has a good head floating capacity and a high CSS strength by grinding magnetic film to a desired film thickness after hardening incompletely the magnetic film and eliminating incompletely a working- degenerated layer due to the grinding process and performing the secondary baking in this state to harden the magnetic film. CONSTITUTION:After the magnetic film coated on a nonmagnetic metallic substrate is subjected to the primary baking to harden incompletely the magnetic film, the magnetic film is ground to a desired film thickness, and the working- degenerated layer due to the grinding process is incompletely eliminated, and the secondary baking is performed in this state to harden the magnetic film. Though the disc which is formed while leaving the working-degenerated layer due to grinding of the magnetic film as it is has a considerably low mechanical strength and causes head crush immediately, the head floating capacity is improved to reduce a maximum extent of floating because an alumina powder (hard nonmagnetic powder) is not projected from the magnetic film. Thus, the disc superior in heat floating stability is obtained.

Abstract: PROBLEM TO BE SOLVED: To improve the strength of a tip by forming a beam material of flange parts and a web part, and forming a right angle corner part, which is formed of an inner surface of the flange part and an outer surface of the web part, in a longitudinal end. SOLUTION: A corner part, which his formed of a pair of flange parts 11 and inner surfaces 11A, 11B of a web part 12, is formed into a circular corner part 13 at the time of molding, and both the flange part 11 are respectively formed with a tip 11B, and while formed with a projecting web part 12B.

In such a case where a H-type beam material 10, of which flange part 10 and of which web part 12 are not separated from each other, is connected to a support side, since a recessed part is not formed like a scallop part, it is hard to generate a breakdown in an end thereof, and strength can be improved.

Abstract: PURPOSE:To prevent a cut sheet from skewing through the agency of a simple mechanical system by providing, on a paper feeding route, a roller interlocking member which is enabled to open and block the paper feeding route through linking to a paper feeding roller. CONSTITUTION:At the point of time when a loop is formed, a loop forming member 11 is pushed down by a cam member 15 so that a paper feeding passage is opened, and at the same time, the tip of a cut sheet 2A, which has been curved into a loop shape, is extended between a platen 7 and a pinch roller 9. By virtue of the restoring force of the cut sheet 2A which has thus been warped, the tip is held properly between the platen 7 and the pinch roller 9. Subsequently, after a continued paper feeding operation through a paper feeding roller 13, since the notch 13B of the paper feeding roller 13 is turned to the side of a paper feeding casette 1, the paper feeding roller 13 is caused to depart from the cut sheet surface, while, at this point of time, the sheet feeding is started by the platen 7, and the cut sheet 2A is wound round the platen 7 regardless of the rotation of the paper feeding roller 13.

Abstract: PURPOSE:To make it possible to enhance the level of the photoelectric converted signals over the whole wavelength be memorizing the most proper scanning time of the photoelectric converting unit of an image sensor for each frequency. CONSTITUTION:The light, which is scattered by a scattering optical element, is condensed at a fixed position of a one-dimentional image sensor 24 for each eave, and a photoelectric converted signal is generated in a time shearing manner in synchronims with the clock pulses of a clock pulse generator 22.

Thus, the photoelectric converted output of the image sensor is optimized so that the sensitivity of the photometer can be enhanced over the whole wavelength.

IPC: H01P7/06
Filed: 1986-05-07
Abstract: PURPOSE:To improve the efficiency by remarkably decreasing the length of a tip of a bias electrode in an oscillator used for a submillimeter band transmitter/recepter more than the height of a waveguide cavity. CONSTITUTION: The diameter of a part in contact with a diode 4 in a bias electrode is (d) and the height is l1. The upper part is a low-pass filter having dimensions of l2-l5. One of the bias power is connected to a bias electrode 7 and the other is connected directly to a cavity 1 to supply a DC or a pulse voltage to the diode 4. The matching between the semiconductor element and an outer cavity is facilitated depending on the shape of the bias electrode and a stem in an ultrahigh frequency oscillator. Thus, the oscillator is easily oscillated in the 100GHz-300GHz through the combination with the inexpensive waveguide cavity.
